Tortll whom.- it may concern:.

Be it known that we, THOMAS MCDONALD and WILLIS MGKEE, citizens of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented new and useful Improvements in Conveyers,

of which the following is aspecification.

Tbeobject .of our invention is to provide means for conveying materials-and in theembodiment of our invention as shown by the accompanying drawingswe have. shown our invention in the formof cooling-beds particularly-designed for conveying plates, bars;

rails, &c... We do not desire, however, to be limited to a cooling-bed, for our invention consists of a new. and improved conveyor and in the construction and combination of parts, all as fully hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevational view of one form of our invention; Fig. 2, a side-elevati'onal view taken on line I I of Fig. 3; Fig. 3, a plan view; Fig. 4, a side elevatlonal view of a modified form of conveyer, and Fig. 5 form of Fig. 4.

Referring to the drawings, 2 represents a set of fixed supports, preferably comprising a series of rails or beams, which latter are supported by a fixed frame 3. Fixed frame 3 is in turn supported by standards 5, extending a plan view of the upwardly from foundations 6. A set of movable supports 1 arranged parallel with and intermediate of the fixed supports, preferably comprising rails or beams similar to the fixed supports, are mounted on a movable frame 8.

' The movable frame 8, the manner of mounting the movable supports thereon, and movable standards 9 for supporting frame 8 are particularly shown by Fig. 2. The lower end of each standard 9 has its hearings on a bellcrank 10. Power-shaft 11 is driven in the forms shown by means of driving-pulley 12 and intermediate gear mechanism comprising pinion 13, gear 14, pinion 15, and gear 16, and in the form of Fig. 1 shaft 11 is provided with an eccentric l7 and a crank 18. Driving-rod 19 connects one bell-crank with crank 18, and the two bell-cranks are joined by connecting-rod 20. Vertical motion is imparted to the movable frame and its set of supports by revolving power-shaft 11. This revolution of the shaft rocks the connected bellcranks and the movable standardsi).

In the form of Fig. 1 we employ for the purpose of effecting a longitudinal movement ofthe movable supports abracket-Ql, secured to the movable frame so as to make contactwvith the eccentric 17 as the latter revolves with shaft 11. By these means we succes' sively raise the load from the fixed supports, carry it forward wizhout sliding friction, and

deposit it at apoint on the fixed supports equal to the length of the longitudinal movement of the movable frame. Combining these two positive-motions of the movable frame gives us a curved or an elliptical motion, and it will be noted by'varying the two motions we are enabled to produce any desirable v curved or elliptical movement of the movable supports. In the form of Fig. lwe preferably employ weights 22 and 23, respectively connected with one of the bell-cranks 10 and with movable standards 9.

The modified form of our invention, as illustrated by Figs. 4 and 5, is particularly designed for conveying rails and similar materials, and it is especially applicable as a cooling-bed for rails. By the employment of this form the whole bed can always be kept full of rails, thereby greatly increasing the capacity over the usual form of cooling-bed. It will also handle the rails in such a manner as notto affect the camber of the rails, without making dents in the rails, as is frequently done under present methods, and, further, the successive rails may be passed over the cooling-bed without being brought into contact with each other. Our invention will therefore deliver the rails in such shape as to greatly minimize the work required in the ra -finishing department.

In the construction shown by the diagrammatic views Figs. 4 and 5 we employ a number of cranks 25, carried on a broken shaft 26.. Said shaft in this instance is to be operated by means simiiar to the means shown and described for operating the power-shaft 11. In addition to the cranks we employ a number of eccentrics '27, the eccentrics in turn being connected up with the bell-cranks with the cranks 25.

In connection with Fig. 1 we have indicated a skidway 30, by which the material is introduced to the conveyer, and in connection with Fig. 4 a car 31, into which the material falls after its passage over the conveyer. Attention is called to the fact that the fall the material is required to make from the conveyer to the car is much less with our construction than is the case with conveyors of this class as heretofore constructed.

\Vhat we claim is 1. In a conveyor, afixed frame having aset of fixed supports, a movable frame having a set of movable supports, and means for effecting a curved movement of the movable frame and its supports for the purpose of giving a positive forward motion to the matcrial being conveyed, substantially as set forth, a I

2. In a conveyor, a fixedframe havingaset of fixed supports, a movable frame having a set of movable supports, and means for effectingan elliptical movement of the movable frame and its supports, substantially as set forth.

3. In a conveyer, a fixed. frame having a set of fixed supports, a movable frame having a set of movable su ports, said movable sup ports parallel with and intermediate of the fixed supports, and means for efiecting a curved movement of the movable frame and its supports for the purpose of giving a positive forward motion to the material being conveyed, substantially as set forth.

4. In a conveyor, a fixed frame having a set of fixed supports, a movable frame having a set of movable supports, and means for effecting a curved movement of the movable frame comprising, a power-shaft, bell-cran ks, movable standards for supporting the mov-, able frame and means connecting the powershaft and the bell-cranks and the power-shaft and the movable frame, substantially as set forth.

5. In a conveyer, a set of fixed supports, a

set 'of movable supports, a power-shaft provided with a crank, means connecting the crank and the movable supports for effecting a vertical movementof the movable supports, and an eccentric mounted on the power-shaft arranged to make contact with a fixed part carried by the movable supports whereby a longitudinal movement of the movable supports is eifected, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
